ABRAHAM PODEL, OF LONG ISLAND CITY, NEW YORK, ASSIGNOR TO ANCHOR CAR AND CLOSURE CORPORATION, OF LONG ISLAND CTIY, NEW YORK, A CORPORATION OF NEW YORK.

Application filed February The presentinvention relates generally to assembling machines and more particularly to a machine for assembling closure caps and liners therefor. V I

1n packaging jellies, jams, and the like, caps applied to the glass containers more for sanitary purposes. and for the exclusion, of dust than to preserve the contents ofthe package, and in such cases hermetic seals are neither necessary nor advisable. The great quantity of such articles consumed renders it necessary to economize as much i as possible in the cost oi packaging by utilizing a glass jar provided with an inexpensive tin cover which irictionally engages the side wall thereof to prevent accidental removal. The appearanceofsuch a cover audits utility are bettered by lining the in nor cover portion With a Waxed paper or a fibrous disk suitably impregnated with paraliin or the like. Also, in forming end seals on jars and vessels in which preservedfruits are packed, requiring hermetic sealsi for proper protection and preservation, such paper or fibrous disks may be increased in thickness sufficiently to form the desired seal between the edge of the vessel and the cover portion of the cap. Such disks are now commonly used for both sealing and protective purposes, and are generally termed liners or sealing waters. The present invention contemplates an improved machine designed particularly for theapplication of such liners to caps, although many of its features are applicable to the assembly of any type of cap with any type of liners or gasket.

Machines have been designed heretofore for the application of cork gaskets to crown cork caps or the like where. the gaskets are relatively thick. In such machines, individual gaskets are separated from a stack by means of a sliding member of predetermined thickness which passes under the stack and engages the edge of the bottom gasket and removes it therefrom in a single operation to its proper position. Such a machinecannot be used commercially with thin liners of paper or fibrous Wafers be. cause the sliding member if it engages the liner will'probably remove several or mutilate the one engaged. Furthermore, such ASSEMBLY MACHINE.

fine adjustments as are required for the proper engagement of thin wafers, necessitates frequent shut-downs and slows up production generally. For these reasons, manufacturers in the past have resorted to manfual insertion of thin liners by girls or others,

whose labor couldbe obtained at a minimum price; but even with cheap labor a consider-.

able percentage of the cost of the assembled capsand liners was occasioned by the labor required to insert the liners.

thicknesses of the liners used thereby Inak ing themachine applicable to all types of liners and caps.

An object of the inventionis to provide a machine which will apply liners to closure caps and the like effectively and eiiiciently with a minimum of time and labor.

Another object of the invention is to provide such a machine applicable to any type 0t liner, irrespective of the thickness there oi, without adjustment, and adapted further to automatically take care of any irregularity in the operation of any of the various mechanisms without shutting down the machine.

Another'objeot of the invention is an improved liner ieeding mechanism wherein the liners are trictio'nally engaged on their plain surfaces and moved from the main supply to a guideway in one operation and arethen moved along the guideway to thejcapswith which they are to be assembled in asecond operation. T I

A more specific object is. the provisionof a rotating disk beneath a stack of liners, said disk having a resilient protuberance thereon adapted to engage the surface of the bottom liner and to stack. 1

Another object of the invention is the pro} remove it from the a and vision of a turnstile adjacent the cap conveyor which is locked in pos'. ion at predetermined intervals, and through which the caps must pass, to position the respective caps for the assembly operation.

ther objects of the invention contemplate a compact machine with its various mechanisms properly positioned to cite tive ly and eificiently perform their various functions, said mechanisms being rugged construction to withstand the usage to which a device of this character is ordinarily subjected.

Described generally, the present invention comprises a cap conveyor for mo ng caps under a reciprocating head which is adapted to press the liners into the respective caps as they pass. A cap positioning device is mounted adjacent the conveyor and prcit erably comprises turnstile which is stopper periodically to retain the caps in pre determined positions in opposition to frictional forces applied by a niovir conveyor, until the assembly operation completed. A magazine for a stack of liners is mounted adjacent the conveyor and has itslowcr por tion opening into a guideway leading to a position between the turnstile and the reciprocating assembly head. lilounted below the magazine is a rotating disk having rubber protuberance adapted to engage the lower surface of the bottom liner in the magazine to move it into the guideway, whereit is engaged by a pair of cam actuated fingers which push it along the guidcway until it is directly above the cap into which it is to be inserted. The operat ons of these mechanisms are correlated so that a cap is properly positioned on the conveyor and a liner is positioned above it before the reciprocating head moves downwardly to assei'uble the two. To prevent the release of caps by the turnstile when liners have not been inserted therein an automatic device is pro vided which engages the respective liners as they pass along the guideway and locks the turnstile in position when a lin r fails to be fed to the cap in the turnstile.

A preferred form of the invention has been chosen for the purpose of illustration and description and is shown in the accompanying drawings, wherein like characters refer to like parts throughout:

iieferring to the drawings, there is shown a conveyor 1 comprising an endless belt 2 mounted upon a pair of pulleys at and 5 on the shafts 6 and 7 respectively. The shaft is adjustably mounted on the framework of the machine by a plate 8 slotted at 9 to receive bolts 10 which permit the tension of the belt to be varied within limited ranges.

the central portion of the belt 2 adjacent the point where the caps and liners are assembled is rigidly supported by means of the angle member 12 bolted to the framework of the machine with a portion extending outwardly under the belt.

Caps are presented by any suitable means, such as the chute 14 described hereinafter, to the belt 2 with their cover portions downward and are moved by the belt toward a turnstile 17. A pair of guides 18 at the respective edges of the belt, supported by a b i kct 19 on the framework of the machine, in the caps in line as they move along the conveyor. Compressed air may be ad- :tted through the tube 13 to facilitate the vc =ent of the caps through the turnstile. e t

l urnstile 17 is mounted on a vertical pin predetermined periods, thereby positioning successive caps under the assembly head irrespective of the motion of the conveyor. By properly adjusting the pin on the end of tne lever the position of the caps on the conveyor may be varied asvdesired to secure correct operation of the various mechanisms.

The rod 38 is hollowed to receive a spring ll which engages a pin l2 extending through a slot 43in the central portion of the rod to form a resilient coi'inection thercbetween. The respective ends cram pin 4-2 extend through and are secure in the bifurcated P ends of a lcver'est which isqiivotcd by a shaft 33 extending through a bearing l5 at the central portion of the lever and having itsrespective ends mounted in hearings all formed in the members The other end of the lever 44 is connected to an eccentric li on shaft 30 toreciprocate the rod 38 in a vertical direction and to cause it to press liners firmly into the caps positioned by the turnstile The connection between the end of the lever a l and theeccentric i? is made through a sleeveet8 which is adapted to adjust the length of the connection so that the head 39 descends onceduring each revolution of the shaft B O suiliciently far to properly insert the liners in the caps. A loci: nut 49 retains the sleeve in its adjusted pos ion and a suitable oil cup 50 supplies a lubricant to tl e eccentric 3:7.

For the purpose of feeding liners to the respective caps, there is provided a guideway 52, leading from themagazine to a point above the positioned'cap. The guideway is formedby a pair of plates 56 and 57, the lower one having a slot 58 extendlongitudinally thereof the with of which is slightly less than the diameter of a liner. The upper surface of the lower plate 57 adjacent the slot iscut away at 59to a depth slightly greater than the thickness of a liner so that a liner placed therein will fit over and be supported by the edges of the" slot and will have its upper surface flush with the upper surface of the plate at to permit the upper plate 5G to be mounted thereon to form the guideway 52 therebetween. The slot in the'lower plate has'its respective ends in the form of semi-circles so that the magazine 54 may be mounted at one end thereof to permit its bottom gasket to rest in one end of the guideway." The other end of the slot is adapted to permit the reciprocating head 39 to pass therethrough. The magazine 5% comprises a base (50 in which a stack of liners is placed and four rods 62 extending upwardly therefrom to sustain the stack in proper position. The base of the magazine and also the end of the plate 57 under the magazine are retained in position by the members 63 secured to the framework by the-bolts (34. The opposite end of the plate 57 may be correctly positioned to permit the reciprocating head 39 to pass through the aperture therein by means of the set screws 65 passing through extensions (5L inlthe plate 82 and engaging other extensions 55 on the plate 56 andby means of the thumb screws-53 which may be loosened to permit the plate to be rotated slightly orinoved longitudinally. 58 in the lower plate permits free engagement of the lower surfaces of linersto move them along the guideway. per plate 56 extends from the base of the magazine to the tnrnstile and'has a circular aperture to'accommodatethe assembly head 39; it may also be'slotted as shown/at 73 to facilitate dislodgment bythe operator of liners which for any) reason become caught in the guideway.

To remove the liners'from the magazine 54, there is'provided a disk 66 mounted on a shaft 67 beneath the magazine and having a rubber protuberance 68 which is adapted to engage the bottom liner in the magazine once during each revolution of the disk. The frictional forces established by thiscngagement are sufficient to remove the bottom liner from the magazine along the guideway 52 a slight distance as shownin Fig; 9. A cam '70 also keyed to the shaft 67 is adapted to engage a cam roller 71 on the arm 72, which is rigidly mounted on a shaft 74 by means of thebolt 75. The upper end of the arm '72 has a linger 76 mounted tl'iereonrotatable about a pin 78 it set screw 79cooperates with a spring 80 to determine the upper limit of the end of the finger so that it will properly engage a liner which has been moved into the guideway by the disk 66; A secondarm 82 is also mounted on the shaft and is similar tot-he arm 72 excepting that it does not i have a cam roller, but isoscillated by'means The slot all 1,668,922

the machine and to the arm 82 to retain the cam roller 71 against the cam 70. The fingers 76 are oscillated about the shaft 71 by means of the cam and are adapted to engage the liner moved into the guideway immediately after the disengagement ot' the rubber protuberance 68 therewith and to move it along the guideway asshown by the clot-dash position of the parts in Fig. 9 until it is directly below the assembly head 39 and directly above a cap positioned by the turnstile. The operation of the arms 72 and S2 and the disk 66 and their timed relation is shown in Figs. 1 and 9 wherein the rubber protuberance 68 is shown in engagement with the bottom gasket in Fig. l and is shown just after disengagement therewith in Fig. 9, the dot-dash position in Fig. 9 showing the location of the fingers a'lterthe liner has been moved to the end of the guideway. To prevent foreign matter from accumulating on the protuberance (58, a rotary brush 85 is provided on shaft which rotates in the opposite direction from the disk 66 and is in continuous engagement therewith. I

The mechanism described above is adapted to position caps, supply liners thereto, and assemble them. However, should the liner feeding mechanism fail to present a liner at the desired time, the turnstile would be released by the pin 25 according to its usual operation and a cap without a liner would be delivered. This is very undesirable since considerable labor would be required to remove such caps from the assembled caps and liners. To prevent this, there is provided a bracket 89 to support an inverted U-shaped member 93 having hearings in the legs thereof to accommodate a spindle 88 having a pair of arms 90 and 91 rigidly attached to its ends and extending respectively over the turnstile 17 and over the guideway 52. An arm 92 rigidly connected to the central por tion of the spindle 88 slidably engages the upper end of a bolt 9% at its outer extremity. Lever 95 slidably engages the lower end of the bolt 94 and is pivoted to the bracket 96 at its center 97 and has a cam roller 98 on its other end held in engagement with the cam 99 by a spring 103. A spring 100 on the belt 9 1 retains the arm 92 and the lever 95 at the extremities of the bolt whereby when the cam 99 rotates, oscillating the lever 95, the sp ndle 88 attached to arm 92 is rocked re iliently to raise and lower the arms 90 and 91. On the ends of these arms 90 and 91. there are pins 101 and 102 adapted to engage respectively the turnstile 17 and a liner in the guideway The lengths of these pins may be adjusted by suitable nuts and are such that it the pin 102 engages a gasket in the guideway 52 as shown in'Figs. l0 and 12, the spring 100 is compressed and the arm 90 and pin 101 are not lowered as far as they would be if the pin 102 should fail to engage a liner, and, there fore, the pin 101 fails to engage the turnstile; but ii a liner is not in position, there is nothing to stop the pin 102, and the spindle 88 under the action of the spring 100 rocks suh ciently to cause the pin 101 to engage and lock the turnstile in position and to prevent it tron'i rotating when released by the locking pin 25. Hence, the cap is prevented from being delivered by the machine until a liner is presented and inserted therein.

11 the cap feeding mechanism fails to function for any reason, the unassembled' liners will be delivered to the chute 103 and when they reach the end thereof will slide under the metal plate 101 and be delivered as shown at 105, whereas the skirts 01 caps moving along the chute will engage the curved portion of the plate and be delivered as shown at 100, thereby separating the un- :IrisJliilJlOil liners from the assembled articles.

The power 'l or operating the machine is supplied to the shalt 107 by means of fast and loose pulleys 108 and 109 and belt 110, which may be connected to any suitable source of power. The belt may be shifted l'roin one pulley to the other for effective and ineliective positions by means of the belt shilter comprising a pair of arms 111 adapted to engage the belt and adapted to be shifted in a horizontal direction by means or" shatt 112 mourned in bearings 11% and having a handle 115. The shaft- 107 is mounted in suitable bearings 116 on the respective sides of the machine having suitable oil cups 117' for the lubrication thereof. There are a pair of bevelled gears 118 and 119 adjacent the ends of the shaft and another gear 120 at the center of the shalt, all keyed thereto for driving the various mechanisms associated therewith. The bevelled gear 118 meshes with a bevelled gear 121 on shatt- 30 to operate the eccentric 47 thereby reciprocating the pressing head 39 for applying liners to the caps. The rotation of the shaft 30 also operates the cam 29, lever 20 and stop 25 for controlling the turnstile 17. The gear 120 at the center of the shaft meshes with an idling gear 12-1 to rota .e gear 125 on shaft (3, upon which the belt driving pulley 4 is mounted for conveying caps as described hereinbel ore. The bevelled gear 119 on shalt 107 meshes with bevelled gear 120 on shaft 67 for driving the liner feeding mechanisms. The rotating brush on shaft 86 connected to the shaft 67 through gear 127 on shaft 80. idling {rear 128 and a gear on shaft 67. The cam 99 adapted to operate the automatic cap feeding device, which locks the turnstile in position when a liner fails to be fed to a positioned cap, rigidly mounted on the shaft 107 as shown at 13%. In this manner, all

g each cap passes through. the turnstile 17, which is stopped periodically by means of the mechanisms o'f themachine are driven from a single shaft extending transversely of the machine facilitating the arrangement of the parts and decreasing the cost oi the machine. For convenience in rotating the shaft 10? for the adjustment of parts and the like, a hand wheel 132 is mounted at one end thereof.

The unasseinbled cap-e may be supplied to the machine by means oi the chute 14 referred to hereinbefore. Preferably, .the chute leads from a supply table 1236 of suitable height having a. curved metallic port ion 137 fitting over one edge of the table with a vertical side portion 188 spaced from the bottom of the curved portion by means; of

the bar 139 and attached thereto by the bolts 140 to form a channel 141 into which an operator may place the caps. The channel is inclined to the horizontal so that the caps therein will roll on the bar 139 into the chute 14 which comprises upper and lower guideways 142 and 143, each formed by a pair of narrow stripsof metal 144 attached to the oppo ite sides of suitable bars 145 by bolts 146. The guideways may be twisted through an angle of substantially ninety degrees so that a cap pla ed in the channel 141 in a vertical position will, during its movement along the chute 14, be turned to its horizontal position and delivered to the conveyor with the cover portion downward as shown in Figs. Qand 13 to 17; At the upper end of the chute an end of one of the metal strips 144 is bent outwardly at 148 to facilitate the entryof the upper edge of the cap into the guideway 142. Therigidity oi? the construction may be increased by the plate 149 attached to the free ends of the guide ways 142 and 143. v

In the operation of the machine. the belt 110 is moved from the idling pulley to the one rigidly attachedtothe shatt 107 to rotate the shafts 30'and 67 extending longitudinally of the machine which operate the liner feeding and mserting mechanism respectively.

A gear 120 at the centerlof shaft 107 op-.

eratcs the conveyor mechanism. As the caps are delivered to'the conveyor 1 by the chute 14 and are moved along the guiderails 18,

the locking pin 25 to position thGIQSPGGClVG caps under-the reciprocating head 39'. Wh le each cap rema nsin its predetermined posi- I tion, the liner feeding mechanism by means of the disk 66 and the rubber protuberance thereon, removes the bottom liner from the stack irnthe magazine and positions it so that it may be engaged. by the fingers 76 and moved along the guideway 52'until it reaches a position directly over the cap in the turnstile 17, whereupon the eccentric 47 moves the pressing head 39 downwardly to" insert the liner into the cap below it. In some instances, the ii r feeding mechanism may fail to present a liner at the desired time, in which case cap will be delivered'with out a liner therein unless otherwise preven ed. To eiiect this. an automatic control is provided. for the turnstile 1''? which coinprises a pin or feeler 102 adapted toengage the liner in the guideway and prevent the pin 101 from moi 'ing downwardly to engage the tiirnstile under the pressure exerted. by the 05; in which case, the turnstilc delivers a cap without interference, but if: the feeler 102 should not engage a liner in theguideway, the spring 100 will tip the lever 92 sufficiently far to causethe pin 101 to engage the turnstile and prevent its rotation under theinfiuence of the frictional engagement with the beltQ, thereby preventing the delivery oi? the cap in which a liner has not been inserted. Such a mechanism isauto-. niatic in all oi? its features and applies liners automatically to closure caps eliminating manual labor excepting that required to place the liners in their magazine and to maintain a supply of capsyfor the conveyor.

InFigs. 18 and 19, there is shown anotherform of: cap positioning mechanism which may be used instead of the turnstile described herei'nbe iore'. This form of position. ing mechanism operates independentlyoi the conveyor mechanism and comprises anoscillatorymember15dmounted on the pin 20 and having one end extending between thev conveyorl and the plate 57 to. engage the caps as they passalongthe guideways 18 at the edges of the conveyor and. retain them i a predetermined position. The other end 01'. the positioning member 156 is attached. by means of a rod 157 to a cam lever 15S pivoted at 159 and having a cam roller 160 thereon adapted to the cam 161 on shaft 30." The cam 161 may be'positionedon the shaft 30 adjacent the eccentric- 47 just as the cam29, described hereinhefore for the pring actuated by cam 09 and lever operation oitqthe pin 25 is positioned. A

spriug lfi attached to the cam lever 138 and the framework of the machine retains the cam roller 160m engagement with the cam The outer end of the positioning member'is shapedso that it willengage the pin 101 to render the spring 162inetfective and pre vent the delivery of a cap when the liner has not beenfinserted therein as described hereinbefore withreference to the automatic control for the turnstile 17'. 7

It willbe seen that the inventiondescribed above. is inexpensive in. construction, simple in operation and applicable to insert :liners of any thicltnessinto closnre caps. Further, by inserting different plates having guide- Ways of the desired size, liners of any description may be used. The various automatic features prevent the delivery of either caps or liners in their unassembled state and the construction of the machine, in general, is such as to facilitate rapid operation with slight attention by the operator.

Since various changesmaybe made in the preferred embodiment without departing from the spirit of the invention, the description herein is to be taken as illustrative and not in a limiting sense. 7
